WELL-DRILLING MACHINE.

:5IE(."JIFICATION forming part of Letters Patent No. 307,572, datedNovember 4, 1884.

Application filed May 16.18%. (No model.)

To all whom it may concern:

Be it known that I, LYOURGUS NELSON, of Florence, in the county ofRutherford and State of Tennessee, have invented a new and ImprovedWVell-Drilling Machine, of which the following isafull, clear, and exactdescription.

My invention relates to improvements in rock-drilling machines; anditconsists in the peculiar construction and arrangement of parts, ashereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawing, forming part of thisspecification, and which is a side elevation of myimproved machine.

I mount the bed-frame a of the machine on wheels I) for portability,using low wheels for affording sufficient stability for working themachine on them to avoid the labor and expense of frequently loading andunloading the machine, and in order to make the machine practicallyoperative on said wheels I mount the driving-shaft 0 on the sills of thebedframe,which enables me to locate the walkingbeam (1 at a point only alittle above the bedframe, and thus lessen the height of the ma chine toan extent rendering it satisfactorily operative on the truck employedfor transporting it. I locate the reel 6 directly over the pivot f ofthe walkingbeam d, and run the drill-rope g from under said reel alongover the beam to thesheave h, and gear the reel with a driving-shaft,2', by means of wheel j andpinion k, for driving it by the crossed beltZ to raise the drill when the pulley m is clutched with the maindriving-shaft c.

In order to feed the drill directly from the reel 6, I have applied thehand-crank o to the shaft 1', and the stop-pawl n to the pinion k, forshifting and setting it to feed the drill.

It will be seen that by the arrangements above described the machine ismade more compact and convenient for transportation, also moreeconomical, and very simple and efficient as to the feeding arrangement.

Having thus fully described my invention, I claim as new and desire to'secure by Letters Patent- 1. In a rock-drill, the combination,with thedriving-shaft c, the walking-beam d, and the sheave h, of the reel 6,located above the pivot of the walkingbeam, the gear-wheel j, the pinion7c, the belt Z, and pawl 72, substantially as herein shown anddescribed.

2. In a rock-drill, the combination, with the frame a, mounted on wheelsI), of the driveshait 0, the walking beam d, the sheave h, the belt Z,the pinion 7c, the shaft t, provided with crank-handle 0, the gear-wheelj, and the reel 6, substantially as herein shown and described.

LYOURGUS NELSON.
